Image processing system including an image processing apparatus and a portable terminal

ABSTRACT

The position and orientation at a time of shooting by a shooting unit of a portable terminal is transmitted to an information processing apparatus. Based on the transmitted position and orientation of the portable terminal and the stored position of an image processing apparatus, the information processing apparatus extracts an image processing apparatus from the shot image and transmits information about the extracted image processing apparatus to the portable terminal. The portable terminal combines the shot image with an option for selecting a function available in the image processing apparatus and displays the combined image on a display unit, based on the information transmitted from the information processing apparatus. When selection of a function is accepted, a screen for operating the selected function is displayed on the display unit of the portable terminal.

This application is based on Japanese Patent Application No. 2010-230358 filed with the Japan Patent Office on Oct. 13, 2010, the entire content of which is hereby incorporated by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an image processing system, a control method, an image processing apparatus, a portable terminal, and an information processing apparatus, and more particularly to an image processing system in which an image processing apparatus is operated by a portable terminal, a control method, the image processing apparatus, the portable terminal, and an information processing apparatus.

2. Description of the Related Art

Image processing apparatuses such as copiers, printers, and MFPs (Multi-Functional Peripherals) including those functions are often used in office environments. Many users have opportunities to use those apparatuses.

On the other hand, with the recent widespread use of portable terminals, users carry portable equipment such as mobile phones having a function of connecting to the Internet, a camera function, and a position detection function and are familiar themselves with using them. Then, as disclosed in, for example, Japanese Laid-Open Patent Publication Nos. 2006-351024 and 2006-091390, some portable information terminals obtain information stored beforehand in association with positional information from a server and combine the information with the captured image, thereby allowing users to view information such as facility usage status or reservation information based on the captured image.

As such image processing apparatuses grow more sophisticated, the operations for users to give operation instructions become complicated. Therefore, the users who use the apparatuses less frequently or the users who use different kinds of apparatuses find it difficult to recognize available functions or find it difficult to use the apparatuses due to the complicated operations.

Then, in light of the widespread use of portable terminals as described above, users may desire to use portable terminals familiar to them even when operating image processing apparatuses.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the following, an embodiment of the present invention will be described with reference to the figures. In the following description, the same parts and components are denoted with the same reference numerals. Their names and functions are also the same.

<System Configuration>

FIG. 1 is a diagram showing a specific example of a configuration of an image processing system according to an embodiment.

Referring to FIG. 1, the image processing system according to the present embodiment includes an MFP (Multi-Functional Peripheral) 100 serving as an image processing apparatus, a portable terminal 200, and a server 300.

The image processing apparatus is not limited to an MFP and may be a printer, a facsimile machine, a copier, or any other similar device having at least one or more image processing functions. MFP 100 is an image processing apparatus that combines these functions.

Portable terminal 200 is, for example, a mobile phone or any other device at least having a camera function, an instruction input function, and a communication function.

The server is a general personal computer or any other similar device.

MFP 100 and potable terminal 200 can communicate with each other and exchange information with each other. Any communication system may be employed in the communication between MFP 100 and portable terminal 200 as long as it is wireless communication. In the example below, wireless communication using Bluetooth® is employed. However, any other communication such as infrared communication or short-distance wireless communication may be employed.

MFP 100 and server 300 can also communicate with each other and exchange information with each other. The communication between MFP 100 and server 300 is either wired or wireless, and any communication system may be employed. Since it is assumed that the image processing system according to the present embodiment is used in an office environment, MFP 100 and server 300 are connected to a wired or wireless LAN (Local Area Network) and exchange information through the network, by way of example.

Portable terminal 200 and server 300 can also communicate with each other and exchange information with each other. Any communication system may be employed in the communication between portable terminal 200 and server 300 as long as it is wireless communication. In the example below, wireless communication using a telephone network is employed. However, infrared communication or short-distance wireless communication may be employed. In the case where portable terminal 200 and server 300 are connected to a wireless LAN, information may be exchanged over the network.

In the following description, different communication systems are employed, specifically, wireless communication using Bluetooth® between MFP 100 and portable terminal 200, communication via a LAN between MFP 100 and server 300, and wireless communication using a telephone network between portable terminal 200 and server 300. However, the same communication system such as communication via a LAN may be employed in each communication.

Although the image processing system in FIG. 1 is configured to include one MFP, one portable terminal, and one server, it may at least include more than one MFP and more than one potable terminal.

<Overall Operations>

The overall operations in the image processing system according to the present embodiment mainly include an MFP information registration operation and an operation for operating the MFP.

Here, “MFP information” refers to information about the MFP included in the image processing system, which is registered in server 300, and includes positional information which is information for specifying the position of MFP 100, communication information which is information for communication, and functional information which is information for specifying the installed available function. Specific examples thereof will be described later. Plural pieces of MFP information stored in server 300 may also referred to as an “MFP list” in the following description.

The MFP information registration operation is performed prior to the operation for operating the MFP and refers to an operation of registering information of MFP 100 in server 300 at a prescribed timing or updating the information of MFP 100 stored in server 300 with the latest information.

The operation for operating the MFP refers to an operation of performing an operation using portable terminal 200 to allow MFP 100 to execute image processing using a function installed in MFP 100. FIG. 2 is a diagram for illustrating the overall operations in the image processing system according to the embodiment. The operation for operating MFP 100 in the image processing system will be described using FIG. 2.

Referring to FIG. 2, a user carrying portable terminal 200 points portable terminal 200 at MFP 100 serving as an operation target to shoot MFP 100 (FIG. 2 (1)). Then, the shot image of MFP 100 serving as an operation target appears on a display screen of portable terminal 200. The functions available in MFP 100 are selectably displayed in the form of tags superimposed on the shot image (FIG. 2 (2)). The user selects a tag representing a function to use, from those tags.

It is noted that the “tag” here refers to an option displayed on the touch panel, and is labeled with a function to be operated, as illustrated in FIG. 2 (2), and displayed in the vicinity of the image of MFP 100 as an operation target so as to be superimposed on the original image. Touching the tag designates to perform the operation corresponding to the function.

For example, when the user selects (touches) a tag indicating a box function which is a function of processing image data stored in a storage area associated with the user (“touch” in FIG. 2 (2)), the screen display of portable terminal 200 switches to a screen for operating the box function of MFP 100 (FIG. 2 (3)). When image data to be processed is selected on the screen (“touch” in FIG. 2 (3)), the screen display of portable terminal 200 further switches to a screen for selecting a method of processing the image data (FIG. 2 (4)). Then, when a processing method is selected on the screen (“touch” in FIG. 2 (4)), image processing based on the operation is executed in MFP 100.

The configuration of each device for performing these operations will be described below.

<Configuration of MFP>

Each function shown in FIG. 7 is a function mainly formed in CPU 10 when CPU 10 reads out a program stored in ROM 11 and executes the program on RAM 12. However, at least part of the functions may be formed by the hardware configuration shown in FIG. 3.

Referring to FIG. 7, as functions for implementing the operations as described above, MFP 100 includes an instruction input unit 101 for accepting an instruction input from operation panel 15 or any other device, a positional information input unit 102 for accepting input of its own positional information from operation panel 15 or from the GPS function not shown in FIG. 3, if any, an address input unit 103 for accepting input of a LAN address and an address in wireless communication using Bluetooth®, a positional information storage unit 104 for storing the positional information accepted by positional information input unit 102, a communication information storage unit 105 for storing the address accepted by address input unit 103, as communication information, a function management unit 106 for managing the functions of MFP 100 and allowing each function to execute an operation, a detection unit 107 for detecting a change of positional information, communication information, and executable functions in MFP 100, an update unit 108 for transmitting the positional information, communication information, and functional information of MFP 100 as MFP information to server 300 to register or update the MFP information in the MFP list in server 300, a screen transmission unit 109 for transmitting required operation screen data among operation screens data stored beforehand, in response to a request from portable terminal 200 as described later, and an instruction specifying unit 110 for specifying the content of an instruction from portable terminal 200.

Since positional obtaining unit 202 and orientation obtaining unit 203 obtain positional information and orientation information, respectively, in response to a shooting instruction from operation panel 25, the information thereof can serve as information of a shooting position and information of a shooting direction, respectively. Then, in the description below, the positional information and orientation information transmitted from portable terminal 200 to server 300 in accordance with the program are also referred to as shooting position information and shooting direction information, respectively.

<Operation Flow for Registration of MFP Information>

FIG. 10 is a flowchart showing a specific example of an operation in MFP 100 performing the MFP information registration operation. The operation shown in the flowchart in FIG. 10 is implemented when CPU 10 reads out a program stored in ROM 11 and executes the program on RAM 12.

Here, the registration of MFP information includes “manual registration” performed by user's operation and “automatic registration” automatically performed without user's operation at a predetermined prescribed timing. Which registration method is employed in registering MFP information is preset in MFP 100, for example, by an administrator. CPU 10 stores the setting.

Referring to FIG. 10, when the “manual registration” is set (YES in step S101), in step S103, CPU 10 executes a predetermined MFP information registration operation in accordance with an operation signal from operation panel 15. Specifically, CPU 10 accepts input of positional information, communication information, and functional information as MFP information in accordance with an operation signal from operation panel 15 and stores the information. Then, the information is transmitted as MFP information to server 300.

On the other hand, when the “automatic registration” is set (NO in step S101), CPU 10 detects positional information, communication information, functional information at the respective prescribed timings. The prescribed timings are, for example, the timing at which MFP 100 is installed, the timing at which network communication is established, or prescribed time intervals. At the instant when the positional information, communication information, or functional information is detected (YES in step S105), CPU 10 compares the detected information with the stored information and determines whether there is a change. If a change is detected (YES in step S107), in step S109, CPU 10 executes a predetermined MFP information registration operation. Specifically, CPU 10 updates the information detected being changed, of the stored positional information, communication information, and functional information, with the latest information and thereafter transmits the MFP information to server 300. Here, only the information that has changed in the MFP information may be transmitted, or the entire MFP information may be transmitted.

Upon receiving the MFP information from MFP 100, server 300 updates the MFP list stored in a prescribed area in HD 33. Specifically, when the MFP information of MFP 100 is not registered in the MFP list, server 300 newly registers the received MFP information. When it has already been registered, server 300 updates the registered MFP information with the received MFP information.

Through this registration operation, the position, address, and installed available functions of each MFP included in the image processing system are registered in server 300.

FIG. 11 is a diagram showing a specific example of the MFP list stored in server 300. Referring to FIG. 11, registered in the MFP list, for each MFP included in the image processing system, are the latitude, longitude, and altitude as positional information, the IP address that is an address for communicating with server 300 and the Bluetooth® address that is an address for communicating with portable terminal 200 as communication information, and presence/absence of the box function and the scan function each as functional information.

The MFP information is not limited to the one shown in FIG. 11. For example, an altitude may not be included in the positional information. In a case where any other communication system is employed, the communication information may be an address according to the communication system. The functional information may include the presence/absence of any other function. In a case where user authentication is performed as described later, whether to permit the use of a function for each user may be included.

In the foregoing description, the MFP information is transmitted from MFP 100 to server 300 for registration or update of the MFP list. Alternatively, in a case where server 300 has an input device, an administrator of the image processing system, for example, may directly input MFP information to server 300. Alternatively, a not-shown communication terminal connected to MFP 100 may transmit MFP information to server 300. In this case, MFP 100 may not be able to communicate with server 300 as long as the communication terminal connected to MFP 100 can communicate with server 300.

<Operation Flow for Operation for Operating MFP>

FIG. 12 is a sequence diagram illustrating a flow of an operation for operating the MFP. FIG. 12 shows a flow of processing in MFP 100 on the left side, a flow of processing in portable terminal 200 at the middle, and a flow of processing in server 300 on the right side. Each operation is implemented when the CPU of each device reads out a program stored in the ROM and executes the program on the RAM.

Referring to FIG. 12, in a state in which application for MFP operation is being activated in portable terminal 200 (step S1), the camera shoots a photo (step S3), and then the information that specifies a shooting position and a shooting direction at portable terminal 200 is transmitted to server 300, whereby the corresponding MFP information is requested (step S3-1).

Server 300 accepts the request from portable terminal 200 and searches for the MFP information of the MFP located in a prescribed range in the shooting direction from the shooting position from portable terminal 200, with reference to each positional information in the stored MFP list (step S5). Then, the corresponding MFP information is transmitted to portable terminal 200 (step S5-1). At portable terminal 200, the application combines the image data from camera 26 with tags for selecting the functions specified by the functional information included in the received MFP information and displays the combined image on operation panel 25 (step S7).

When the tag is selected (touched) on the image displayed on operation panel 25 of portable terminal 200 (step S9), a request for a screen is given to MFP 100 together with the information that specifies the function corresponding to the selected tag (step S9-1).

MFP 100 transmits screen data for operating a process by the requested function to the requestor portable terminal 200 (step S11). Here, the screen data stored beforehand to be displayed on its own operation panel 15 may be transmitted to portable terminal 200, or the corresponding screen data stored for portable terminal 200 may be transmitted, or if the information specifying portable terminal 200 is transmitted together from the requestor portable terminal 200, the screen data stored beforehand to be displayed on its own operation panel 15 may be transmitted after being subjected to resolution conversion based on the information of portable terminal 200.

Here, the screen data itself is transmitted from MFP 100 to portable terminal 200. However, in a case where the program activated in portable terminal 200 has a function of generating an operation screen, only the information necessary for the operation screen may be transmitted from MFP 100 to portable terminal 200, and screen data may be generated in portable terminal 200 based on the transmitted information.

At portable terminal 200, an operation screen is displayed based on the transmitted screen data. Then, when a touch operation is made on the screen (step S13), information specifying the designated position is transmitted as an operation signal to MFP 100 (step S13-1). The operation signal transmitted here is, for example, an operation signal that specifies the position designated on operation panel 25 by the relative position thereof to the displayed screen. As another example, in a case where the application running on portable terminal 200 has a function of analyzing the screen data from MFP 100, the operation content corresponding to the position designated on operation panel 25 may be specified, and an operation signal indicating the content may be transmitted to MFP 100.

MFP 100 specifies the operation content based on the screen data transmitted to portable terminal 200 and the designated position represented by the received operation signal (step S15). Here, when an additional operation is required to perform the selected function, MFP 100 transmits the screen data for the next operation screen in accordance with the program for executing the selected function of its own. In this case, the operation above in steps S11 to S15 is repeated until the function is executed.

Then, when all the operations necessary to execute the function are specified, MFP 100 executes image processing using the function in accordance with the operations (step S17).

In a case where the program activated in portable terminal 200 has a function of generating a control signal, a control signal for MFP 100 may be generated in accordance with the screen data and the position designated on operation panel 25 and transmitted in place of the operation signal in step S13-1. In this case, MFP 100 executes image processing in accordance with the control signal from portable terminal 200.

The operation in portable terminal 200 will be described in detail below using the flowcharts. FIG. 13, FIG. 14, and FIG. 15 are flowcharts each illustrating an operation in portable terminal 200 performing an operation for operating the MFP. FIG. 13 is a flowchart illustrating an operation for displaying a tag superimposed on a shot image, FIG. 14 is a flowchart illustrating an operation in a case where a box function is selected as a function to be operated, and FIG. 15 is a flowchart illustrating an operation in a case where a scan function is selected as a function to be operated. The operations shown in the flowcharts in FIG. 13, FIG. 14, and FIG. 15 are implemented when CPU 20 reads out a program stored in ROM 21 corresponding to the application for operating the MFP and executes the read program on RAM 22.

Referring to FIG. 13, in a state in which CPU 20 is executing the application for operating the MFP (YES in step S201), and if camera 26 is shooting a photo (YES in step S203), then in step S205, CPU 20 transmits information representing a shooting position and a shooting direction to server 300 and requests transmission of the MFP information of the corresponding MFP.

When a response is received from server 300 (YES in step S207), and when the response is the MFP information (NO in step S209), CPU 20 executes a process for combining tags for selecting the functions specified by the functional information of the MFP information with the image data obtained by shooting, and displaying the combined image.

Specifically, when the functional information shows that the box function is available (YES in step S211), in step S213, CPU 20 calculates the MFP display position in the image data obtained by shooting based on the positional information of the MFP included in the MFP information, and displays a tag for designating start of the operation for the box function so as to be combined at the calculated position or in the vicinity thereof. In the example of the screen in FIG. 2 (2), image data of the tag labeled with “BOX” is stored beforehand, and screen data is generated by combining the image data at the calculated position and is displayed on operation panel 25.

When the functional information shows that the scan function is available (YES in step S215), in step S217, CPU 20 calculates the MFP display position in the image data obtained by shooting based on the positional information of the MFP included in the MFP information, and displays a tag for designating start of the operations for the scan function so as to be combined in the calculated position or in the vicinity thereof. In the example of the screen in FIG. 2 (2), image data of the tag labeled with “scan” is stored beforehand, and image data is generated by combining the image data at the calculated position and is displayed on operation panel 25.

Next, referring to FIG. 14, when the tag representing the box function is selected from the displayed tags (YES in step S301), in step S303, CPU 20 reads out the Bluetooth® address of MFP 100 from the communication information of the MFP information and initiates communication using Bluetooth® with MFP 100. Then, in step S305, the screen data for operating the process by the box function is transmitted to MFP 100.

Upon receiving the corresponding screen data from MFP 100, in step S307, CPU 20 allows operation panel 25 to display an operation screen based on the image data. Upon accepting the operation based on the operation screen, that is, the touch operation on the operation screen (YES in step S309 and NO in step S311), in step S313, CPU 20 transmits a signal specifying the designated position on the operation screen as an operation signal to MFP 100.

The operation thereafter returns to step S305 described above, and the following operation is repeated until the end of operation (YES in step S311). More specifically, a signal specifying the designated position on the operation screen is transmitted as an operation signal to MFP 100 every time a touch operation on the operation screen is accepted, and the next screen data is then transmitted from MFP 100. Accordingly, the operation screens for inputting operations in the box function appear one after another, as depicted in FIG. 2 (3) (4), so that the operations necessary for the process by the box function are accepted on operation panel 25 of portable terminal 200.

When the tag representing the scan function is selected from the displayed tags, CPU 20 also performs an operation similar to the operation illustrated in FIG. 14. Specifically, referring to FIG. 15, when the tag representing the scan function is selected from the displayed tags (YES in step S401), in step S403, CPU 20 reads out the Bluetooth® address of MFP 100 from the communication information of the MFP information and initiates communication using Bluetooth® with MFP 100. Then, in step S405, screen data for operating the process by the scan function is transmitted to MFP 100.

Upon receiving the corresponding screen data from MFP 100, in step S407, CPU 20 allows operation panel 25 to display an operation screen based on the image data. Upon accepting an operation based on the operation screen, that is, a touch operation on the operation screen (YES in step S409 and NO in step S411), in step S413, CPU 20 transmits a signal specifying the designated position on the operation screen as an operation signal to MFP 100.

The operation thereafter returns to step S405 described above, and the following operation is repeated until the end of operation (YES in step S411). More specifically, a signal specifying the designated position on the operation screen is transmitted as an operation signal to MFP 100 every time a touch operation on the operation screen is accepted, and the next screen data is then transmitted from MFP 100. Accordingly, the operation screens for inputting the operations in the box function appear one after another in a similar manner as in FIG. 2 (3) (4), so that the operations necessary for the process by the scan function are accepted on operation panel 25 of portable terminal 200.

Effects of Embodiment

Through the operation as described above in the image processing system according to the present embodiment, MFP 100 can be operated using portable terminal 200 as described in the overall operations.

In the foregoing example, the box function and the scan function are illustrated as examples of functions of MFP 100. As the recent MFPs have been more sophisticated, even more functions are installed and available. In such a case, many options for selecting a function to be operated from those functions as well as options for operation in those functions are displayed on the operation screens appearing on operation panel 15 of MFP 100. Therefore, such operation screens are difficult to operate for the users unfamiliar with them. Moreover, since the functions installed in MFPs and the available functions vary among MFPs, the users unfamiliar with them may be unable to promptly determine whether the desired function is available in the MFP to be operated.

In such a case, in the image processing system according to the present embodiment, the user can activate the dedicated application in portable terminal 200 familiar to them and take a picture of the MFP, so that the functions available in the MFP are displayed as tags. Then, when the user selects one from those tags, the operation screen for the function to be operated appears on operation panel 25 of portable terminal 200. The user can operate MFP 100 through operation input on the screen.

Accordingly, the users can recognize the available functions at a glance and, in addition, can operate the functions easily. In addition, even when MFP 100 is located at a distance from the users, the users do not have to move there and can operate MFP 100 with portable terminal 200 they carry.

Modified Embodiment

In MFP 100, user authentication may be performed in using a function. Such a case will now be described as a modified embodiment.

FIG. 16 is a block diagram showing a specific example of a functional configuration of MFP 100 according to the modified embodiment. Each function shown in FIG. 16 is also a function mainly formed in CPU 10 when CPU 10 reads out a program stored in ROM 11 and executes the program on RAM 12. However, at least part of the functions may be formed by the hardware configuration shown in FIG. 3.

Referring to FIG. 16, as functions for implementing the operation described above, MFP 100 according to the modified embodiment further includes, in addition to the functions shown in FIG. 7, a login information input unit 111 for accepting input of login information and an authentication unit 112 for performing user authentication.

In the modified embodiment, function management unit 106 stores the installed and available functions and stores information of users permitted to use for each function, or user information that is information of the functions permitted to be used for each user.

FIG. 17 is a sequence diagram illustrating a flow of an operation for operating the MFP in the image processing system according to the modified embodiment. The flow of the operation illustrated in FIG. 17 differs from the flow of the operation shown in FIG. 12 in that an operation for user authentication as illustrated in step S10 is additionally performed.

Specifically, in the image processing system according to the modified embodiment, a function is selected at portable terminal 200 in step S9, and a request for a screen is given to MFP 100 together with the information that specifies the function corresponding to the tag selected in step S9-1. Then, MFP 100 determines whether the selected function requires user authentication. Then, if user authentication is required, an operation for user authentication in step S10 is performed.

More specifically, if user authentication is required, in step S10-1, MFP 100 transmits screen data for inputting login information for use in user authentication, in place of the requested screen data, to portable terminal 200. When input of login information is accepted in accordance with the screen in step S10-2, then in step S10-3, MFP 100 refers to the stored user information and determines whether to permit the use of the selected function. If it is determined that the use is permitted, that is, if user authentication is successful for the selected function, the requested screen data is transmitted to portable terminal 200 in step S11.

In this manner, a function that requires user authentication, for example, such as a box function, can also be provided with security and with enhanced operability.

Although input of login information is accepted in this modified embodiment, MFP 100 may store the correspondence between the Bluetooth® address of portable terminal 200 and user information and may perform user authentication based on the address when portable terminal 200 requests screen data from MFP 100 in step S9-1. Alternatively, in place of user authentication in this manner, authentication may be performed using a passkey (PIN code) in the communication using Bluetooth® between MFP 100 and portable terminal 200.

The present invention also provides a program for allowing MFP 100 as described above to execute the foregoing operation, a program for allowing portable terminal 200 to execute the foregoing operation, and a program for allowing server 300 to execute the foregoing operation. Such programs may be stored in a computer-readable recording medium accompanying a computer, such as a flexible disk, a CD-ROM (Compact Disk-Read Only Memory), a ROM (Read Only Memory), a RAM (Random Access Memory), and a memory card, and be provided as a program product. Alternatively, the programs may be stored in a recording medium such as a hard disk contained in a computer. The programs may be downloaded via a network.

The program in accordance with the present invention may allow the process to be executed by invoking necessary modules, among program modules provided as a part of Operating System (OS) of a computer, in a prescribed sequence at a prescribed timing. In this case, the modules are not included in the program itself and the process is executed in cooperation with OS. The program that does not include such modules may also be included in the program in accordance with the present invention.

Furthermore, the program in accordance with the present invention may be embedded in a part of another program. In this case, the modules included in another program are not included in the program itself, and the process is executed in cooperation with another program. Such a program embedded in another program may also be included in the program in accordance with the present invention.

The provided program product is installed in a program storage unit such as a hard disk for execution. It is noted that the program product includes the program itself and a recording medium encoded with the program.
